FtheF

This is a new rendition of the original ``Freddie the
Friedlander'' for physical model of the bowed string plus artificial
performer. This version adds visuals and color in an attempt to
image-by-synesthesia fabrication. For this purpose visuals' script
goes in parallel to the time line of measures with harmony and
counterpoint. Visuals work as additional voice in the composition on
which all elements work in contrast against each other, one by one
instead of a solo role. As well as in the original version, melody and
harmonic progressions are based on Miles Davis' ``Freddie the
Freeloader'' but using intervals and chords given by the
Bohlen-Pierce scale of thirteen harmonic steps. Colors and
nuances are also geared towards the elements of Davis' music in
addition to arrays of different stringed objects with different
tensions depending on context.

Sound sources result of bowing a string allow for continuous
input of gestural energy to hold a sound product of vibrations given by
friction between a bow and a string. With high static friction, the
bow sticks to the string for a moment, drags the string along until it
bounces back (reflecting) to its original position, thus generating
vibrations in a process known as Helmholtz Motion. The part of
the bow that touches the strings is made of horsehair rubbed with
rosin. In contrast to plucking, bowing maintains a continuous rich
harmonic spectrum in sound providing features for gesture
manipulation based on bow motion and pressure.

F the F is a multiphonic piece meant to be viewed and
listened on a Dolby surround audio system. This piece was composed on
Common Music, Common Lisp Music and other open source software for
visuals on a Linux system.
